HOWTO: Fancontrol

[Mr Wonka]

And if you want to have it startup on boot.

#!/bin/sh
#
# Fancontrol start script.
#

set -e

# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol/.fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

test -f $DAEMON || exit 0

. /lib/lsb/init-functions


case "$1" in
	start)
		log_begin_msg "Starting fancontrol daemon..."
		start-stop-daemon --start -o -q -m -b -p $PIDFILE -x $DAEMON
		log_end_msg $?
		;;
	stop)
		log_begin_msg "Stopping fancontrol daemon..."
		start-stop-daemon --stop -o -q -p $PIDFILE
		log_end_msg $?
		;;
	force-reload|restart)
		sh $0 stop
		sh $0 start
		;;
	*)
		log_success_msg "Usage: /etc/init.d/fancontrol {start|stop|restart|force-reload}"
		log_success_msg "  start - starts system-wide fancontrol service"
		log_success_msg "  stop  - stops system-wide fancontrol service"
		log_success_msg "  restart, force-reload - starts a new system-wide fancontrol service"
		exit 1
		;;
esac

exit 0

Stick this in a file called 'fancontrol' in your init.d startup scripts. eg.

/etc/init.d/fancontrol

Add this to your startup scripts in the usual way.

Don't forget to

$ sudo chmod 0755 /etc/init.d/fancontrol

and create a symlink to that script in rc3.d, for example.

$ sudo ln -s /etc/init.d/fancontrol /etc/rc3.d/S99fancontrol

(thanks for that, by the way!)

I fixed the code in pwmconfig, and it still doesn't work...any ideas?

*edit* Nevermind...I fixed it

Hi all, thanks for this great guide, worked perfectly for me so far (yet to reboot ).
One thing of note that occured for me using the script kindly provided above:

 sudo /etc/init.d/fancontrol start
 * Starting fancontrol daemon...
start-stop-daemon: Unable to open pidfile `/var/run/fancontrol/.fancontrol-pid' for writing: No such file or directory

# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol/.fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

I had to change the PIDFILE path to:

# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

I don't know if this was something specific to me....... But incase it helps others.

I would seriously have a heart-attack just by trying this (I don't even need for it to _not_ work O.o). Just reading the red disclaimer sends shivers down my spine.

Hello, the pwmconfig patch isn't helping the situation in my system.
I still get the
"/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed" error.



Any help is appreciated.

Are you very sure you corrected the pwmconfig file right?

If so: it may be right, you may not have any pwm configurable fans in your computer. Most Dells don't, for instance, even the new ones.

Do you get any results in fancontrol under Windows?

[|cassidy|]

Yes, I've triple checked the procedure

I've got a desktop pc, via kt266 chipset and in windows I control the fans' speed using Speedfan.

I did a search on the forum and found this
http://www.ubuntuforums.org/showthre...ight=pwmconfig

I have the same motherboard chipset and the same kernel version.

I really gotta lower these fans, I've got low temperatures and a fan that sounds like a vacuum cleaner.

Did you do all the things in here? If you go "sensors", what does it output?
